# ABSTRACT: registry for type constraints
=pod
=head1 NAME
Moose::Meta::TypeConstraint::Registry - registry for type constraints
=head1 VERSION
version 2.0401
=head1 DESCRIPTION
This class is a registry that maps type constraint names to
L<Moose::Meta::TypeConstraint> objects.
Currently, it is only used internally by
L<Moose::Util::TypeConstraints>, which creates a single global
registry.
=head1 INHERITANCE
C<Moose::Meta::TypeConstraint::Registry> is a subclass of
L<Class::MOP::Object>.
=head1 METHODS
=over 4
=item B<< Moose::Meta::TypeConstraint::Registry->new(%options) >>
This creates a new registry object based on the provided C<%options>:
=over 8
=item * parent_registry
This is an optional L<Moose::Meta::TypeConstraint::Registry>
object.
=item * type_constraints
This is hash reference of type names to type objects. This is
optional. Constraints can be added to the registry after it is
created.
=back
=item B<< $registry->get_parent_registry >>
Returns the registry's parent registry, if it has one.
=item B<< $registry->has_parent_registry >>
Returns true if the registry has a parent.
=item B<< $registry->set_parent_registry($registry) >>
Sets the parent registry.
=item B<< $registry->get_type_constraint($type_name) >>
This returns the L<Moose::Meta::TypeConstraint> object from the
registry for the given name, if one exists.
=item B<< $registry->has_type_constraint($type_name) >>
Returns true if the registry has a type of the given name.
=item B<< $registry->add_type_constraint($type) >>
Adds a new L<Moose::Meta::TypeConstraint> object to the registry.
=item B<< $registry->find_type_constraint($type_name) >>
This method looks in the current registry for the named type. If the
type is not found, then this method will look in the registry's
parent, if it has one.
